- HAND-STAMP.

SPECIFICATION forming part of Letters Patent No. 256,243, dated April 11, 1882.

' Application filed August 13, 1881. (Nomodeh) To all whom it may concern:

Be it known that 1 WILLIAM H. POOLE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hand-Stamps; and I hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the same, reference being bad to the accompanying drawings, forming a part hereof, and in which- Figure 1 represents a side elevation, Fig. 2 a front view, and Fig. 3 a rear View, of my improved hand-stamp. Fig. 4 represen tsalongitudinal side view of the removable die 2'.

Like letters of reference indicate like parts.

In the drawings, A represents the arm of an ordinary hand-stamp carrying a reciprocating plunger, B, from the sides of which project two pins, d, which hold each one endof a connecting bar, e, the other end of which is pivoted at d to a lever, f. Said levers are held by and play upon a rod, g. To the inner side of said levers is attached a stud, 8, upon which plays a pawl, 0, against aratchet-wheel, t, fastenedto the rear end of the shafts or drums k. Said pawls are held against the wheels t by a coiled spring, n, attached to it, and to a stud, 12, also attached to the levers f. v

To the upper end of the leversf are pivoted bars h at h, in the front ends of which play the journals of an inking-roller,j, and to the rear ends of which are attached springs 7%, which serve to press said roller against the die 43 and inking-plate j. The inking-plate is provided with two arms or brackets, 3' which pass on each side of the arm A, and through all of which passes a pin, j which serves to hold the plate j in its place. Theinking-rollerj is provided with rims or ends of larger diameter than theroller, which ends run upon the face of the plunger B, but which pass by the ends of the types 71 and the ends of the inking-platej so as to permit the face of the roller j to come in contact with them.

Upon each side of the base anddating wheels m are attached drums k, inclosed in a'box or chamber covered by lids q, of which one is shown open in Figs.1 and 2. Said lids are held closed by means of a spring, 1', wound around the pintle of their hinge.

A milled head, a, is attached to the outer end of the shafts It, and a long inking-ribbon, l, is attached at its ends to the drums k and wound upon one ofthem, as shown.

A plate, 0, is attached to the base and provided with dies in the usual manner, and to and across the rear end of which is attached a hook, c, and to the front end is attached a pair of hooks, p, made adjustable by screw-threads thereon working into the ends of the block 0, or otherwise, so as to hold the ticket T in its proper place.

The spring it draws the pawl 0 against the wheel 25; but when it is desired that it should not work it is merely drawn back beyond the center of the stud s, when the same action of the spring will hold it, as shown in dotted outline. As the ribbon l is Wound and unwound alternately from one drum to the other by the action of the pawls 0 at each operation, one of the pawls must alternately be placed as just described.

The operation of my hand-stamp is shown in Fig. 1, in which the parts shown in full lines show thenormal position of the apparatus and the broken lines show the position of the parts when the ticket is being stamped. At each operation one of the pawls 0 turns one of the drums 7c and winds the ribbon upon it. After it is all wound upon that drum its pawl o is thrown back, and the other pawl is engaged, which then turns its drum, upon which the ribbon is then wound, and thus alternately. The inking-plate j is smeared with ink on its under surface, against which and the diet the roller plays at each operation.

The bar 0 is curved so as nottointerfere with the projecting ends of the die 15; but the die 2' might be made of a length equal to the width of the plunger B. Then the bars 6 might be made straight. It is only necessary that the pin d shall be to one side of the line of thepins g d to cause the machinery to operate.

I claim- 1. In a hand-stamp provided with an automatically-adjustable inking-ribbon, plunger, and roller inking apparatus, the combination of the ribbon, theplunger, and base, oscillating levers f, attached to the base behind and below the inking-ribbon, and mechanism, as described, to actuate said levers and ribbon, said levers carrying at their free ends an automatically adjustable inking roller, substantially as specified.

2. In a hand-stamp provided with an automaticallyadjustable inking -ribbon, plunger, printing-surfaces both upon its bed and plunger, and inking-plate, the combination of the oscillating leversf, attached to the-base behind and below the drums 7c, and provided with an automaticallyadjustable inking-roller and mechanism, substantially as described, whereby said levers, roller, and drums are actuated, substantially as specified.

3. In a hand-stamp providedwith drums 7:, one on each side of its base, printing-surfaces on both its base and plunger, and inking-plate j, the combination of the levers f, pivoted to the base and carrying at their free ends an automatically-adjustable inking-roller, with the base and. plunger, pawls 0, and mechanism, substantiallyas described, connectin g the plunger and levers f, constructed to operate substantially as specified.

4. In a hand-stamp provided with printingsurfaces both upon its bed and plunger, the combination of the base 0 and plunger B, ribbon l, and drums k on each side of. the base, provided with ratchet-wheels t, inking-plate j, with the levers f, carrying the automaticallyadjustable roller j, pawls 0, and bars 6, substantially as specified.

5. In a hand-stamp provided with printingsurfaces upon its bed and plunger, the ribbon l, drums 70 on each side of its base, provided with ratchet-Wheels t, in combination with the levers f, bars h, pivoted at h, and carrying roller j, spring h bars a, pawl 0, spring a, and base 0 and plunger B, constructed to operate substantially as specified.
